The orebodies are controlled by quartz porphyry and faults. It generally occurred near the contact zone of quartz porphyry and Silurian formation or in the fault fracture zones, which are related to the late Yanshan tectonic movement. As to the ore-forming fluids of Damajianshan Cu-As deposit of Lvchun district, the mineralization temperature decreases and meanwhile the mineralization salinity increases from the lower to the upper part and the homogenization temperature changes a little, that implies there is a progressive evolution for the fluid from lower to upper and Na-rich system to Ca-rich system. In this area, the Cu-As and W ore-forming fluids flow characteristics are different, there was 2 phases of metallogenic characteristics, so it’s considered to be a structurally controlled hydrothermal vein type deposit.
